For anyone wanting to attach to these events then use the following

 public class OverrideUserCreate : ApplicationEventHandler
{
    public OverrideUserCreate()
    {
        umbraco.BusinessLogic.User.New += User_New;
        umbraco.BusinessLogic.User.Saving += User_Saving;
    }

    void User_Saving(umbraco.BusinessLogic.User sender, EventArgs e)
    {
        //your code here
    }

    void User_New(umbraco.BusinessLogic.User sender, EventArgs e)
    {
        //your code here
    }
}

Although you cannot send the user an unencrypted password from here as it is already hashed before the events fire. In the end i had to create my own user control which i added to the user dashboard section to list current users and manage password resetting and email sending from there.
